RADIATOR.

SPECIFICATION forming part of Letters Patent No. 495,284, dated April11,1893. Application filed October 29. 1891. Renewed March 1'7, 1893-Serial N0.466,542. (No model.)

To all whom it may concern.-

Be it known that I, MARGARET A. WILOOX,

a citizen of the United States, residing at Chi cago, in the county ofCook' and State of Illi-' nois, have invented certain new and 'usefulImprovements in Radiators, of which tl1e fol-- lowing is aspecification, reference being had therein to the accompanying drawings.

This improvement is designed to provide a tions of parts hereinaftermore particularly described and thendefinitely claimed.

In the accompanying drawings-Figure 1 is a front elevation of myimproved radiator.

Fig. 2 is a view with the front removed, and partly insection, thebetter to show the pipes,

drc. Fig. 3 is a vertical transverse central section of the same.

Referring now .to the drawings byfigures: 1 represents the back and 2the front casting, the latter being cast of ornamental form,

but the precise configuration may be left to suit the taste of themanufacturer. In the center is a tube or flue 3, preferably oblong incross section and broadening from a point about two-fifths of its lengthfrom the bottom into a pear-shaped combustion chamber 4 open at front,but is closed by a (preferably glass) door 5. Inside of this, andcommunicating with the gas supply, is a gas pipe 6, having burners 7, ofany approved form or style, to burn the gas supplied to said burnersthrough the pipe 6. Although, for greater convenience, I prefer gas,natural or artificial, it is evident that the burners may be of theclass known as vapor burners, in which case gasoline may be supplied tothe pipe 6, in any convenient manner.

At 9 and 10 are shown pipes, which lead from and to a heating apparatus,preferably a combined cooker and heater, such as shown in myapplication, Serial No. 410,239, filed of even date herewith; but I donot limit myself to said heater, as any other may be employed. Startingfrom the pipe 9, the pipe passes along the bottom of the radiator up theleft side ofthe chamber 4 and the tube 3, then over to the extreme leftof the radiator, thence down to the bottom, alongwhich it passes to theright-hand side of the chamber 4, up said chamber and the tube 3, to thetop, thence downward to the bottom, along the bottom to the left side ofthe chamber 4, up the left side of said chamber and flue as before,across the top, nearly to the left side of the radiator, thencedownward, nearly to the bottom, along the bottom to the right side ofchamber 4, up the same and the tube, as before, across the top to nearlythe right side of the radiator, then down the side, along the bottom,and again up the left side of the chamber 4 and pipe 3, and socontinuing around down 7 the'outside until the end of the pipe, at 10,

is reached, which is the return pipe to the heater.

The operation is as follows: The heating 7o apparatus (not shown) beingsupplied with water and fuel, either solid or gaseous,.the fire islighted and the gas in the burners 7 also, and a circulation is inducedby the con joint action of the heater and the burners 7, in the systemof piping running from 9 to 10, and more especially by the action of theburners 7 on that portion of the pipingcontained in the chamber 4 andtube 3, which is exposed to the direct action of the heat from the gasand the heated products of combustion arising therefrom, that pass upthe tube 3. The heated products of combustion may pass off through theflue 11 at the top of the tube 3 to the outer atmosphere, or they maypass to a ventilating apparatus, but which, as it forms no partof theinvention here claimed, is not described. In some cases, I leave off theglass door 5, andset a reflector 12 behind the gas jets to deflect theheat from them into the V room that would otherwise be absorbed by theback of the radiator and the wall behind it. With this arrangement, andwith the products of combustion passing out through the flue 11, a verygood system of heating and ventilation may be obtained, without theventilating apparatus above referred to, asair necessary to keep up thecombustion of the gas is all drawn in from the cold air lying at thebottom of the room, which is combined with 10 7 heat, the water may bekept at a suitable demuch carbonic acid gas given off from the lungs ofthe persons in the room,which is thus carried off as fast as it falls tothe floor. The apparatus in this form is thus much like an open fire inits healthful effects, to say nothing of the cheerful aspect of theblazing of the gas, which may be seen through the opening in the beheightened, if pre front, and which may ferred, by colored glass, orother devices.

This radiator, in conjunction with my heater, to which reference hasheretofore been made, will be found to be very convenient in operation,as it can be used in different ways.

For instance, in the fall, or spring, when it may not be necessary tohave a very great tion shown, as it is evident that my invention maybevaried in many particulars without departing from the essential featuresthereof.v

I deem it important that the piping shall be arranged to pass throughthe heating chamber, then down the outside thereof and again through theheating chamber several times 1n succession, as by this means a veryrapid circulation of the water is kept up, owing to the heatbeingappliedto the pipes at so many different points in the circuit, and for thesame reason, all of the radiating pipes are kept at a comparatively evenand high heat instead of many of them being cooler than others, as inthe old style of pipe radiators.

I am aware that it has been proposed in a system of supplying heat tocities to reheat the water at different places along the line byseparate furnaces, each requiring a separate attendant. This I considera very different arrangement from mine which is a combined heater andradiator preferably heated by gas, in which there is a continuouscircuit of piping where the water is frequently heated and radiated inone passage through the same radiator.

What I claim as my invention is 1. A combined heater and radiatorinclosed in a single casing and having a heating chamber and acontinuous circuit of water piping, several sections of saidcircuitpassing through said heater to absorb heat, and other sectionsarranged in the circuit between the water heating sections, and actingas radiating surfacesto distribute the heat absorbed by the Water,substantially as described.

2. The combination in a radiator, of gas burners 7, the tapering chamber4 inclosing said burners, the flue 3 above said chamber 4, a system ofpiping lining the walls of said chamber 4 and passing through flue 3,said piping being arranged to pass up through the chamber 4 and flue 3to heat the water and then down the outside thereof, to act as aradiator, several times in succession in a continuouscircuit, thusmaking a perfect circulation of the water, substantially asidescribed.

3. The combination of a radiator casing 2, a central heating'chamber 4therein, a flue 3 abovethe chambe ga burner within said chamber 4, asystem of radiating water piping, passing up through said chamber anddue on one side, out through the hue 3 to the spacebetween the radiatorcasing and the flue, down said space to act as a radiator, and thenagain entering the heatingchamber and flue and passing upthrough thesame on the opposite side, passes down through the radiator case ontheoppositeside it first passed down and again up the heating chamberand line, several times in succession, whereby a continuous circulationis obtained, substantially as described.

In testimony whereof I affix my signature, in

presence of two witnesses,this 8th day of 0c tober, 1891.
